Question

I want to have a Link and when the user clicks on it it should do the following:

• Saving the a key into the session
• Open a new Window with another JSF page
• It should NOT reload the current page

I don’t know how to solve the problem.
When I save the key and open the new Window, the key is empty.
Maybe the process of saving the key is too slow?
And how to prevent the page from reloading?

This is my current code:

JavaScript

function openWin2(url)
{
     var w = 800;
     var h = window.innerHeight - 100;
     var left = ((screen.width-w)/2);
     var top = ((screen.height-h)/2);
     window.open(url, 'Tax', 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+top+', left='+left);
}

xhtml

<ui:repeat value="#{main.list}" var="items">
    <h:commandLink action="#{main.setClickedId(items.itemId)}">
        <table onclick="openWin2('immobilie.xhtml')"><tr><td>Hello</td></tr></table>
    </h:commandLink>
</ui:repeat>

ManagedBean
Save

public void setClickedId(String clickedId) {
    this.clickedId = clickedId;

    FacesContext context = FacesContext.getCurrentInstance();
    Map<String, Object> map = context.getExternalContext().getSessionMap();
    if(map.containsKey("id")){map.remove("id");}
    map.put("id", clickedId);
}

Load

FacesContext context = FacesContext.getCurrentInstance();
immoId = context.getExternalContext().getSessionMap().get("id").toString();

Answer 1

I have spotted the fail by myself.
The problem was, that the JSF Page did not parse the JSF Tags.
From:

<h:outputText value="#{items.itemId" />

I got nothing as output.
That’s why I thought that the JSF page failed on calling the methods.
But this was not the problem. The problem was my URL. That’s my code to open the second page:

openWin2('immobilie.xhtml')

But thats wrong. It has to be

openWin2('faces/immobilie.xhtml')

I got the solution from here.
